GENERAL DESCRIPTION flee emanatin machine c se 9, lust ate the present invention is driven or operated. ,by a

conventional type of electric motor, said motor being of start and stop type, which operates only during machine operations, or when the traveling carriage is being moved in a return direction. The electric motor is controlled and machine operation is initiated by means of three release or motor bars, including a Main release bar, 2. Vertical Feed release bar, and a Skip-Tabulating release bar, and, in addition, said motor is controlled, and machine operation is initiated, by various so-called motorized control keys.

The machine embodying th present invention 7 is provided with a front-feed type of traveling carriage, which is shiftable in a tabulating direction under influence of a spring-actuated drum or reel mechanism and is shiftable in return direction by the machine operating motor, or said carriage may also be shifted in a return direction manually, if desired. The traveling carriage carries a platen roll for presenting record material to the printing elements, said laten roll being movable from printing position to front feeding position and vice versa, to facilitate the insertion of the record material around the platen roll. Ordinarily the traveling carriage is automatically tabulated near the end of machine operation, after the printing mechanism has functioned, from one columnar position to the next. A manually operable key is provided for tabulating the traveling carriage from one columnar position to th next whenever desirable. Like- Wise the traveling carriage may be skip-tabulated through intervening columnar positions to predetermined columnar positions by the use of the skip-tabulating starting bar to initiate machine operation.

When the traveling carriage reaches the end of its tabulating movement, mechanism controlled thereby renders the carriage return mechanism operative to return said traveling carriage to its extreme right-hand or starting position. Likewise the machine is provided with the usual manipulative return bars for returning the traveling carriage from tabulated position through intervening columnar positions, to predetermined columnar positions.

Machines of the type embodying the present invention are usually provided with six totalizers, one or more of which may be an add-subtract totalizer, often referred to as a balance totalizer or a crossfooter. It is not desirable to limit the machine to any particular number or type of totalizers, as the number and type of totalizer may be increased or decreased to meet the particular needs of the business system to which the machine is being applied. As presently arranged, the machine has one add-subtract or balance totalizer and five adding totalizers.

The machine embodying the present invention is provided with a plurality of denominational row of amount keys, which control the positioning of corresponding differential actuators in adding and subtracting operations, said actuators in turn controlling the positioning of corresponding type carriers and corresponding totalizer wheels selected for engagement therewith. Any or all of the six totalizers may be selected for engagement with the amount actuators in adding operations by means of the traveling carriage in predetermined columnar positions thereof. Likewise the balance totalizer may be selected for engagement with the amount actuators in subtracting operations by means of the traveling carriage in predetermined columnar positions thereof.

The machine embodying the present invention is provided with a plurality of control keys including a Balance key and a Sub-Balance key for selecting and conditioning the balance totalizer for balance and sub-balance, or resetting and reading, operations. The Balance key is a socalled motorized key, in that depression thereof initiates machine operation, and, as said Balance key is always used in conjunction with the Sub- Balance key-that is, depression of the Sub-Balance key carries the Balance key downwardly in unison therewithit is evident that use of either of these keys initiates machine operation. The control keys also include Total keys for the other five totalizers, depression of any one of which causes the corresponding totalizer to be totalized or reset, and said control keys likewise include a Sub-Total key, which is used in conjunction with the Total keys to sub-totalize or read the corresponding totalizers, The control keys also include a Subtract key for selecting the Balance t0- talizer for subtract operations, an Add key for selecting the Balance totalizer for add operations, a Non-Add key, which non-adds all the totalizers so that the amount keys may be used as printing keys only, and a Release key for releasing any depressed amount key and. any depressed control key which is not motorized.

The balance totalizer of the present machine is provided with overdraft mechanism, similar to that disclosed in United States Patent No. 2,243,- 806, issued May 27, 1941, to Laurence N. Lehman, for transposing the complementary figure of an overdraft to a positive figure. The operator is informed of the existence of an overdraft in the balance totalizer by the locking of the Balance key and the Sub-Balance key, which is efiected automatically when the balance totalizer changes from a positive condition to a negative condition.

The overdraft mechanism includes a Sub- Credit Balance key and a Credit Balance key, both of which are motorized, for initiating subcredit operations and/or credit balance operations, respectively, in which the complementary amount of an overdraft contained in the balance totalizer is transposed to a positive amount or a true negative balance, and is recorded upon the record material. In a sub-credit balance operation, the complementary amount of the overdraft is returned to the balance totalizer. Such operation is often referred to as a reading of the overdraft. In a credit balance operation, the balance totalizer is left in a zeroized condition, thi type of operation being often referred to as a resetting of the overdraft.

The present machine is provided with a full complement of typewriter keys for typing data, of a descriptive nature or otherwise, upon the record material, However, the typewriter mechanism is a matter of choice and may be omitted if desirable.

The typewriter keys and the typewriter space bar actuates a typewriter escapement mechanism which letter-spaces the traveling carriage in a tabulating direction. During tabulating movement of the traveling carriage under influence of any of the manual or automatic tabulating means to be described presently, the typewriter escapement mechanism is temporarily rendered inoperative. However, said escapement mechanism again becomes effective upon arrival of the traveling carriage in any columnar position.

The machine embodying the present invention is provided with mechanism for depressing the Sub-Balance key and/or the Balance key when the-traveling carriage arrives incolumnar positions corresponding, respectively, to these keys, I while traveling in a tabulating direction.

. The Balance key and the Sub-Balance key are depressed by their respective electromagnets or solenoids. one of which is connected to the Sula- Balance key and the other of which is connected to the Balance key. The energization of the electromagnets is controlled by a switch mecha nis'm', which is operated bytappets located in predetermined columnar positions'on the traveling-carriage, in cooperationv with variable connection between said tappets and the switch mechanism. The tappets for actuating the switch mechanism areby-pass tappet and are effective only Whenthe traveling carriage is movingin.jatabulatingdirection.

, Mechanism'unjder control of the traveling carriagetabulating mechanism renders the variable connection ineffective to operate the switch mech- ,anism at all times except when the traveling carriage is moving in a tab-ulating direction under -,Manu ally, operated switch mechanisms are pro-- vided;for disconnecting the source of electrical energyto; the solenoids-to render them inoperavewh a-d sirab ,,The ,switch operating tappets are of different lengths, the sub balance tappet being the longer of the two, and consequently, when-the traveling carriage is tabulated to the sub-balance column, said.- tappet ;depresse the switch .mechanism full distance to energize both of the solenoids to cause 2 :"ille-,..Sub-Ba1ance .key and the Balance key lto be'depressed, Whichit will be recalled, is nec essary in, orderto select and condition the balance totaliser for a sub-balance operation. :When the, traveling carriage: is tabulated to the balance, column, the balancetappet, which is I e shorterythan the. sub-balance tappet, depresses theswitch; mechanism partial distance to energize only the solenoid for the Balanceheywheroupon said solenoid depresses said Balance key to cause the balance totalizer to be selected and conditioned fora balance operation. s I

Theeolenoid-aetuated key-depressing mechanism, whichi controlled by the traveling car main left frame 30, secured to a machine base 3i and maintained in spaced relationship to each other. by various cross frames, bars, and rods. The mechanism of the machine is enclosed in a suitable case or cabinet 32 (Fig. 3) which is likewise secured to the machine base 3 i.

The machine is operated bya conventional type of electric motor of the start-stop type, in that it functions only during machine operation. Operation of the. machine is initiated by a main release bar 33 (Fig. 1), which closes the motor switch and engages the clutch mechanism, which connects the motor to the machine mechanism. In addition to the Main release bar 33 (Fig.1), machine operation may be initiated by aSkip Tabulating release bar 34 or a Vertical Feed release b-artfi, each of-said bars cooperating with extensions from the'Main release bar 33,,which underlie the corresponding bars and through which said bars, when depressed, simultaneously depress said. Main release bar 33 toinitiate op eration of the machine. The downward portion of the bar 33 (Fig. J.) has alined slots which, in cooperation with corresponding studs 36 and '37 secured in the right frame 25, shiftably mount said release bar 33.

The downward portion of the bar 33 carries a stud 38, which engages a slot 39 in the rear end of a bar 40, the forward end of which is pivoted on a stud 41 in the right frame 29. A latch 42 is shiftably mounted on the bar as by means of a slot 43 in it rearward end, whichengages a stud 4 5 in said bar, and bymeans ofa slot 45 in the front end of saidlatch 42, which engages the stationary stud 4!. The latch 42 has anupward hook shaped extension 4%, which cooperates with a stud ll in a lever 68 free on the studB i. A spring 49, tensione'd between the latch 42 and the lever 48, urges said latch rearwardly to nor, really maintain the hook-shaped extension 4*? thereof in engagement with the stud M, as shown in Fig. l. A rearward extension of the lever d8 carries a stud. 5c, engaged by a slot in an upward extension of an arm 5! free on a stud 52 secured in the right frame 2,9. V

A slotted downwardjextension of. the arm 5i forms fingers 53 andfid, which cooperate with a means of a stud 58 carriedby said slide, in co operation with a slot in said arm and bymeans of a slot 59 in the lower end of said slide, in

.riage, is shown here as app-lied to the Balance keyfand the sub Bala nce-key. However, it is not the desire to limit thismechanism to anyparticular control keys, forit could obviously beused .in connection with any or all of the control keys,

DETAlLElJ DESCRIPTION $-The. mechanismof the machine is supported by 'a main right frame ZQ(Figs;4 and Bland a cooperation withv a stud BE in said arm 57. .A spring GLtensioned between the stud 6t and a stud in the slide 56, urges said slide downwardly to normally maintain the bent-over portion 55 in engagement with the fingers 53 and. 54, as shown here (Fig. l), to form a disconnectable operating connection between the arms 5| and ill. An upward extension of the arm 51 (Fig. 1) isengaged by a stud 52 in a bell crank 53 free on a-stud 64 in the frame 29. A spring-65 -(Fig. 1) urges the bell crank 6,3 clockwise, which. through the stud 62, urges the arm 5? counterclockwise ;to normally maintain a stud 68, carried by said arm, in yielding engagement with shoulder 6! formed in an opening inan arm 68 free one, stud iiflsecured in the frame 29. The arm 68 has pivotally connected thereto the forward end of a 'pitman NJ, the rearward end of which is bifurcated to embrace a stationary stud H, said pitman carrying a stud 12, which engages a slot'iin'an upward extension of a clutch 7 slide 56 and the fingers 53 and 54, to the arm then through the lever 48, the latch 42, and the bar 40 to the release bar 33, to yieldingly urge and normally maintain said bar in its upward or undepressed position, as shown here.

Depression of the release bar 33 (Fig. 1), through the stud 38, rocks the bar 48 and the latch 42 clockwise, causing the extension 46, in cooperation with the stud 41, to rock the lever 48 counter-clockwise. Counter-clockwise movement of the lever 43, through the stud 55, rocks the arm 5| clockwise, said arm in turn, through the fingers 53 and 54, in cooperation with the bent-over portion 55 of the slide 55, rocking said slide and the arm 5'! also clockwise to disengage the stud 66 from the shoulder 51. This frees the arm 68, the pitman TB, and the lever 13 to the action of a spring (not shown) connected to said lever 13, which immediately rocks said parts counterclockwise to engage the clutch mechanism and simultaneously close the switch 'for the operating motor, to initiate operation of the machine.

Near the end of machine operation, the lever 13 (Fig. 1) is restored clockwise in the usual manner, which, through the pitman f0, also restores the arm 68 clockwise until the shoulder 6'! moves beyond the stud 68, whereupon said stud engages said shoulder to retain said parts in restored position, thereby terminating operation of the machine.

In case the release bar 33 (Fig. l) is inadvertently or otherwise retained depressed at the end of machine operations, repeat operations of the machine are prevented in the following manner. When the release bar 33 is retained depressed at the end of machine operation, restoring clockwise movement of the arm 68, as explained above, causes a surface 74 thereon to engage the stud 58 to shift the slide 58 inwardly against the action of the spring 6!, to move the bent-over portion 55 out of engagement with the finger 53 and into a clearance opening formed by the finger 53 to permit the arm 5'! to be restored [counter-clockwise by the bell crank (53 independently of the arm 5!, so that the stud 65 may engage the shoulder El to prevent repeat operations of the machine.

When pressure is removed from the release bar 33, the spring 49 restores the lever 48 clockwise, which, through the stud 50, also restores the arm 5| counter-clockwise to permit the bentover portion 55 to again move out of the clearance opening into engagement with the fingers 53 and 54 to again operatively connect said arms 5! and 57. It is to be understood that restoring clockwise movement of the lever B and the arm 68 moves the shoulder 67 a. substantial distance beyond the stud 55 to provide sufficient overthrow to disengage the bent-over portion 55 from the fingers 53 and 54 in the manner explained above, after which said lever 13 and said arm 68 are returned counter-clockwise until said shoulder 67 engages said stud 66.

The action of the latch 42 in preventing maloperation of the machine, in connection with automatic sub-balance and balance operations, will be explained later herein.

Keyboard and difierential mechanism- Traveling carriage and typewriter mechanism The present machine is provided with a plurality of denominational rows of amount keys (not shown), each row of which has cooperating therewith a corresponding differential actuator '16 (Fig. 9) operatively connected to a corresponding printer positioning segment 11 free on a shaft F8 supported by the main frames 29 and 30. The segment :"i is connected by a link 19 to a corresponding type sector 83. In adding and subtracting operations, the actuator T6 is positioned by the corresponding depressed amount key and, through the segment H and the link 19, positions the corresponding type sector accordingly, so that, upon operation of the impression mechanism, the value of the depressed amount key wiil be recorded upon record material supported by a platen roll 8! supported in the framework of a traveling carriage 82 mounted for horizontal shifting movement upon ways 83 and 8 (Fig. 3) secured to the machine case 32. The platen 8! is of the front-feed or throat-opening type, in that said platen may be moved from a printing position to a front-feeding position and vice versa, to facilitate the insertion and removal of record material into and from the front-feed throat thereof.

The segment 'i'! (Fig, 9) is yieldingly connected by a spring 85 to a transverse bar 86 of a leading frame having an invariable back-and-forth movement, the initial rearward movement positioning the actuator 18 and the printing sector 80 in accordance with the value of the depressed amount key, and the return forward movement of said leading frame, near the end of machine operation, restoring said actuator and type sector to zero or home position. The actuator 16 has, on its rear end, rack teeth 8'! (Fig. 9), which cooperate with corresponding wheels of the various totalizers for positioning said wheels in accordance with the values represented by the depressed amount key.

The machine embodying the present invention is provided at its rear end with six totalizers arranged in vertical pairs. However, as only the balance totalizer, or crossfooter, is essential to a proper disclosure of the present invention, it is believed sufficient to illustrate and describe only the corresponding wheel 88 (Fig. 9) for the balance totalizer in connection with the actuator 16.

In adding operations, after the actuator 16 (Fig. 9) has been positioned under influence of the depressed amount key, the corresponding wheel 83 of the balance totalizer is engaged with the rack teeth 8'! of said actuator, and return forward movement thereof revolves said wheel in an additive direction to enter therein a value corresponding to said depressed amount key. In subtracting operations, the corresponding wheel 88 of the balance totalizer is engaged with the rack teeth 8? prior to initial rearward movement of the actuator '15, which movement revolves said wheel in a subtractive direction to subtract therefrom an amount corresponding to the depressed amount key.

In balance and sub-balance operations, the wheel 88 of the balance totalizer is engaged with the rack teeth 8'! prior to initial rearward movement of the actuator l6, which movement revolves said wheel in a subtractive direction to zero position, to position said actuator and the type sector St in accordance with the value standing on said totalizer wheel 88. In balance operations, the wheel 88 is disengaged from the teeth 81 prior to return forward movement of the actuator l6, and, as a result, said wheel remains in a zeroized condition. In sub-balance operations, the wheel 88 remains in engagement with the teeth 87 during return forward movement of the actuator 16, and, as a result, said wheel is restored 9 to its original position. This constitutesv the only difference between a balance operation and a subbalance operation.

Carriage cscopement mechanism The traveling carriage 32 (Fig. 3) is urged to.- ward the left, or in a tabulating direction, by a spring-actuated drum (not shown), which is connected to said carriage by a draw band 90 in cooperation with a stud secured in the carriage framework. The travelin carriage is normally restrained against movement in a tabulating direction, under influence of the band 93, by the usual traveling carriage escapement mechanism comprising a rack 9! (Fig, 3) secured to the traveling carriage framework iii! and extending the full length of said carriage. The rack 91 meshes with a pinion 12 secured on the upper end of a vertical shaft Q3 (Figs. 3 and 6) journaled in a bushing ts secured in an escapement cross frame 95, which extends between and is secured to the main frames 29 and Secured on the lower end of the Verticalshaft 93 is an escapement ratchet wheel t6 having escapement teeth which cooperate wtih an escapement pawl mechanism comprising an escapementreleasepawl Si and an escapement retaining dog (not shown), both of which are mounted on an escapement arm 98 journaled on a screw stud $9 threaded in the escapement frame 95 (Figs. 6 and 8). a

The present machine is provided with a full complement of typewriter keys, which, through their corresponding levers let (Fig. 3), actuate corresponding tyge bars iiii to type data, of a descriptive nature or otherwise, upon the record material supported by the platen roll 8|. The levers Hit actuate the usual universal bar [92, which, through connections not shown here but well known in the art and fully disclosed in the patents referred to near the beginning of this specification, actuates the escapement arm 98 (Figs. 6 and 8) to letter-space the traveling carriage 82 in the regular and usual manner.

In addition to the actuation of the escapement mechanism by the typewriter keys, mechanism is provided for disengaging the escapement release pawl iii to release the traveling carriage 82 for movement in a tabulating direction to its various columnar positions, as will he explained in detail later.

Traveling carriage return mechanism Motor-operated means is provided for returning the traveling from tabulated positions to extreme right-hand or starting position, or for returning said traveling carriage to predetermined columnar position.

A carriage return rack Hi3 (Fig. 3) is shiftably mounted on brackets secured to the traveling carriage framework and the teeth of said rack mesh with gear teeth in a clutch driven member 4&4 free on a vertical shaft i535 journaled in a bracket H33 secured to the machine case 32. The clutch driven member ltd has, on its upper edge, clutch teeth arranged to be engaged with corre spending clutch teeth on the lower face of a clutch driving member it secured on the shaft 05, which shaft is operatively connected to the machine operating motor and is continuously rotated thereby while said motor is operating- An annula-r groove in the hub portion of the driven member Hid is engaged by one end of a shifting lever lt (Fig. 3) pivoted on a screw stud in the bracket Hit, the other end of said lever being linked by a closely coiled spring N29 to one end of a lever 10 I I0 pivoted on a screw stud in the machine case 32. The other end of the lever H0 freely engages a slot in the rear end of a lever H2 pivoted on a screw stud H3 in the case 32. The forward end of the lever H2 (Fig. 3) is pivotally connected to the downward end of a plunger H4 supported for vertical shifting movement in a boring in the case 32. A camming surface on the upper end of the plunger il l booperates with a corresponding camming surface on an enlarged portion of a slide H5 mounted in a slot in the case 32. The slide H5 has an upward projection H5, which is engaged by an operating finger mounted on the traveling carriage d2,when said carriage reaches the terminus of its movement in a tabulating direction, and this engagement shifts said slide i is toward the left.

Movement of the slide I W toward the left causes the, camming surface on its right-hand end, in cooperation with the corresponding cammin surface on the plunger lid, to shift said plunger downwardly to rock the lever H2 counter-clockwise, as viewed in Fig. 3. Countcr-c1ockwise movement of the lever l 52 rocks the lever i ill in a contrary direction, which, through the spring H39, rocks the lever N18 to shift the clutch driven member Id l upwardly to engage the teeth on its upper edge with the teeth in the clutch driving member lei. Simultaneously with the engaging of the clutch teeth, the lever Hit also operates a mercury switch ill (Fig. 3) to complete the electrical circuit to the operating motor to initiate operation of said motor for carriage return purposes. Operation of the motor drives the shaft M5, the clutch driving member Nil, and the clutch driven member iii i, causing said driven member, in cooperation with the rack it, to move the traveling carriage 82 in return direction.

When the traveling carriage 82 reaches starting position, a permanent stop located thereon, in cooperation with a corresponding stop bar, terminates further movement of said carriage in a return direction. The manner in which the carriage return rack m3 is mounted on the carriage 82 permits said rack 'to be shifted toward the right and downwardly in relation to said traveling carriage by the clutch driven member 104, after the return movement of said carriage has been terminated. Downward movement of the rack H13, in cooperation with a flange I it formed on the lower edge of the clutch driven member Hi l, shifts said driven member downwardly to disengage the teeth in its upper edge from the corresponding teeth in the clutch driving member lill, to restore said clutch driven member and the control switch Ill to ineffective positions, as shown in Fig. 3.

The slide [l5 (Fig. 3) is provided with a protruding finger piece I I9 (Fig. 3) for the purpose of manually operatin said slide to return the traveling carriage from any tabulated position to starting position. The present machine is also equipped with mechanism for causing, the traveling carriage to be selectively returned from tabulated positions to predetermined columnar positions. However, as this mechanism has no particular bearing upon the present invention, it is not disclosed herein. If desirable, a full disclosure of this selective, return mechanism may be had by reference to the Christian Patent No. 2,082,098.

Traveling carriage tabulatzng mechanism The present machine is provided with tabulating mechanism for controlling the columnar p0- sitioning of the traveling carriage to bring dif- 'nection with the lever I21.

ferent columnar portions of the record material into register with the printing mechanism for the recording of data relative to various transactions. This tabulating mechanism is often referred to as the "accounting machine tabulating mechanism to distinguish it from the typewriter tabulating and/or letter-spacing mechanism, as these two mechanisms function independently of each other.

Ordinarily the tabulating mechanism functions automatically near the end of each machine operation to tabulate the carriage from one columnar position to the next. In additon, the carriage may be skip-tabulated to predetermined columnar positions by use of the Skip-Tabulating release bar 34 (Fig. 1) to initiate machine operation. Moreover, the carriage may be tabulated from one columnar position to another whenever desired by the manipulation of a Tabulating key conveniently located on the accounting machine keyboard.

Removably mounted on the front of the traveling carriage framework 82 (Figs. 3 and 4) is a tabulating bar I20, which supports adjustable control blocks I2I arranged in positions on said bar corresponding to the various columnar positions of the traveling carriage 82 and the record material supported by the platen 8I. The control blocks I2I may be adjusted laterally in any position desired upon the bar I20, and said bar I20 may be readily removed from the traveling carriage 82 in case it is desired to substitute another bar having the various control blocks properly arranged thereon for a different accounting system.

The control blocks I2I (Fig. 4) have thereon a tabulating stop projection I22, which cooperates with the upper end of a carriage stop bar I23 and an escapement control bar I24, the upper ends of which bars fit freely in a slot formed in an enlarged portion of a tabulating frame I25 extending between and secured to the frames 29 and 30. The stop bar I23 (Figs. 4 and has in its lower end a slot which is engaged by a stud I26 in a lever I21 pivoted on a screw stud I28 threaded in the tabulating frame I25. An enlarged downward surface on the lever I21 overlies a stud I29 in the lower end of an escapement disabling bar I30 mounted to shift vertically in a slot formed in an enlarged portion I3I of the frame I25. A plate I32 (Fig. 6), secured to the enlarged portion I3I, retains the bar I 30 in the slot formed in said enlarged portion. A spring I33, tensioned between the lever I21 and a bent-over portion of the plate I32, urges said lever counter-clockwise, as viewed here, to normally maintain an enlarged portion on its upper edge in contact with a lower stop surface formed on the portion I3I.

The stop bar I23 (Figs. 4, 5, and 11) carries a stud I35, which extends through a slot in the lower end of the escapement control bar I24 to form an operating connection between these two bars. The lower end of the escapement contro1 bar I24 is pivotally connected by a stud I36 to one end of a lever I31 free on the stud I28, said lever having an enlarged lower portion which overlies the stud I29 in exactly the same manner as explained in con- An enlarged upper portion of the lever I31 is arranged to cooperate with the stop surface on the portion I3I of the frame I25 in exactly the same manner as explained in connection with the lever I21.

The left-hand end of the lever I21 (Figs. 4 and 5) overlies the right-hand end of a lever I38 free on a screw stud I39 threaded in the frame I25.

" The left-hand end of the lever I30 engages a slot in an operating arm I40, which is actuated automatically and/or manually in various ways to rock the lever I 38 counter-clockwise when it is desired to tabulate the traveling carriage 82. Counter-clockwise movement of the lever I38 rocks the lever I21 clockwise, against the action of the spring I33, permitting the stud I26, in cooperation with the slot in the lower end of the tabulating stop bar I23, to release said bar to the action of a torsion spring I4 I, which underlies the stud I35. The spring I4I carries the stop bar I23 upwardly in unison with clockwise movement of the lever I21, and, during clockwise movement of said lever, a square stud I42 (Fig. 5), carried thereby, moves beyond the tooth of a latch I43 free on a stud I44 in the frame I25, whereupon a spring I45 rocks said latch clockwise to move the tooth thereon into the path of said stud I42 to obstruct return counter-clockwise movement of said lever I21 and return downward movement of said stop bar I23. Clockwise movement of the latch I43, under action of the spring I45, causes a bump I45 thereon, in cooperation with the right-hand edge of the stop bar I23, to shift said bar slightly toward the left, as viewed here.

Upward movement of the bar I23, through the stud I35 (Figs. 4, 5, and 11), in cooperation with the slot in the lower end of the bar I24, carries said bar I24 upwardly in unison therewith, rocking the lever I31 clockwise in unison with the lever I21. When the bar I24 reaches the extent of its upward movement, a notch I 41 in its edge moves into alinement with a square stud I48 in an arm I49 pivoted on a screw stud I50 threaded in the frame I25. Aspring I5I (Fig, 4) urges the arm I49 clockwise to normally maintain a shoulder thereon in contact with a stop stud I52 in the frame I25. When the notch I 41 moves into alinement with the stud I48, a spring I53 (Figs. 4 and 11) urges the bar I 24 toward the left, or counter-clockwise, to engage said notch I41 with said stud I48 to yieldingly retain said bar I24 in its upward position.

Upward movement of the bar I23 and consequent clockwise movement of the lever I21 (Figs. 4, 5, and 6), through the stud I29, shift the bar I30 downwardly against the action of a spring I54 tensioned between the plate I32 and a finger of a bell crank I55 free on a stud in a bent-over extension of said plate I32, said finger of said bell crank engaging a slot in the lower end of said bar I30. Downward movement of the bar I 30 rocks t e bell crank I55 (Fig. 6) counter-clockwise against the action of the spring I54, which movement, through a link I55 pivotally connecting an arm of said bell crank I55 to a lever I51 free on a stud in the escapement frame 95, rocks said lever I 51 clockwise against the action of a spring I58. Clockwise movement of the lever I51, through a link I59 pivotally connecting a rearward extension of said lever to a rearward extension of a yoke I50 free on a shaft I6I supported by the frame 95, rocks said yoke IEO also clockwise. Clockwise movement of the yoke I30 causes an upwardly extending arm I62 thereof to engage the escapement retaining pawl 91 (Figs. 6 and 8) and rock said pawl out of engagement with the teeth of the escapement ratchet 95 to free said ratchet and the traveling carriage 82 for movement in a tabulating direction under influence of the spring-actuated draw band 90, Which immediately starts said carriage moving in a tabulating direction. The traveling carriage 82 continues to move in a tabulating direction, or toward the right, as viewed in Fig. 4,, until the stop lug 922 on the control block .l2l located in the next columnar position strikes the upper end of the bar 1123 and carries said bar toward the right in unison therewith, until the right-hand edge of the bar I23 contacts the righthand wall of the slot the tabulating frame I25, to terminate tabulating movement of said traveling carriage 82. Clockwise or right-hand movement of the stop bar E23, in cooperation with the hump I46 (Figs. 4 and 5) on the latch rocks said latch counter-clockwise against the action of the spring I45 to disengage said latch from the stud M2 to release the lever l2? and the stop bar J23 to the action of the spring i553, which immediately rocks said parts counter-clockwise and downwardly, respectively. This moves the upper end of the stop bar H3 out of the path of the lug I22 and beneath the upper end of the escapement control bar 32 3, which does not protrude as far to the left Fig. l) the bar i223 and con sequently up to this time has not been engaged by the lug i252 and therefore is still in its upward position in the path of said lug. After the lug i22 has carried the stop bar 823 into contact with the wall of the slot in the frame I25, the traveling carriage rebounds slightly from said step. This momentarily frees the :bar I23, and it is during this period that the spring 133 (Figs. 4 and 5) returns said bar downwardly out of the path of the lu m2. When the traveling carriage 82 returns from the reboundin movement referred to above, the lug in contacts the upper end of the escapement control bar 124 (Figs. .4, 6, and ll) and rocks said bar toward the right, as viewed here, against the action of the spring it, to disengage the notch till from the stud M8, whereupon the spring we is free to rock the bell crank I55 clockwise to restore the bar 130 upwardly, which, through the stud ltd, rocks the lever I3? (Fig. 11) counter-clockwise to move the bar its downwardlyout of the .path of the lug .122. Clockwise return movement of the bell crank 15% (Figs. (Sand 8), through the link 156, the lever R51, and the link 559, returns theyoke 1GB and the upwardly extending arm i 62 thereof counter-clockwise to reengage the escapement retaining pawl ill with the teeth of the ratchet 96 to locate and retain the travelingcarriage .82 in its tabulated columnar position.

By. reference to Fig. i, it will be noted that the right-hand upper ends of the bars M3 and E24 have thereon similar angular surfaces, whichpermit the stop lugs i22 to by-pass said bars incase the traveling carriage is inadvertentl moved in a return direction while said bars are intheir upward positions. The elongated slot in the lower end of the bar liisd 'igs. 4 and 5), in cooperation with the stud 92E, and the springactuatedcarm v1 .48 in cooperation with the bar .I 24, hermitsaid bars to be depressed when the lugs I22 byrpass their upper ends, in case the traveling carriage is moved in a return direction whensaid bars are in, their upward positions, thereby pre venting damageto the tabulating mechanism.

' Garriage controlof machine releasing The machine rel-easing mechanism, shown in Fig, l and explained earlier herein, is normally locked'against operation when the traveling carriage is out of columnar positions. However, when said carriage is in columnar positions, this locking mechanism is rendered ineffective.

' Each of the control blocks iii (Fig. 1) has a tappet E65, which, cooperation with an uptllnfiilextension 565 of a control lever ,lilfi free on av stud IS! in a tabulating frame. I25 (Fig, 4), depresses said lever I66, when the travelin cal,- riage 82 is in any of its columnar positions. Dee pression of the lever I66, through a wire link [68 connecting said lever to av crank 59 secured on a shaft I'EB journaled in the main frames 29 and it, rocks said crank and said shaft counterclockwise, as viewed in Fig. 1. Also securedon the shaft ill! and moving counter-clockwise in unison therewith is an arm I'll, a finger of which, in cooperation with a stud I12 in a control lever H3 free on a stud I'M in the right frame 29, rocks said lever clockwise against the action of a spring I75. Clockwise movement of the lever I13 withdraws an obstructing shoulder, formed in a recessed portion thereof, from a square stud I16 in the lever 48 and moves a clearance portion of said recess opposite said stud, to free saidlever 38 for counter-clockwise releasing movement, upon depression of any one of the startin bars 33, 34, and 35, as explained earlier herein.

When the traveling carriage 82 moves out of columnar position, the corresponding tappet I54 (Fig. 1) is withdrawn from the upward extension I55 of the lever I66, thereby .releasing said lever and the control lever H3 to the action of the spring I15, which immediately restores said lever H3 counter-clockwise to engage the shoulder thereon with the stud H6 to obstruct releasing movement counter-clockwise of the lever 48.

It is therefore evident that the mechanism shown. in Fig. 1, and explained above, locks the machine against operation when the traveling carriage is out of columnar position.

Carriage control of totaliaer junctions Any of the six totalizers with which the machine is equipped may be selected for addition by means of corresponding hanging bar levers [1! (Fig. 1.) supported by the stud H37 in cooperation with corresponding tappets M8 on the control blocks ,l2l. Likewise, the balance totalizer may be selected for subtraction by means of a subtract hanging bar lever, not shown, but similar to the lever ill, in cooperation with a correspond ing subtract tappet on any one or more of the control blocks E25. Furthermore, all of the six totalizers may be non-added by means of a nonadd hanging bar lever (not shown) in cooperation with corresponding non-add tappets on any one or more of the control blocks l2l.

The mechanism under control of the traveling carriage 82 in its columnar positions, for selecting the various totalizers for addition, for selecting the balance totalizers forsubtraction, and for non-adding all of the totalizers, is fully disclosed in one or more of the patentsreferred to hereinbefore.

Skip-tahula'tiflg mechanism In skip-tabulating operations, depression of the Skip-Tabulating release bar 34 (Fig. 1), through a link Ila (Fig. 4), rocks a latch 2853 over a bentover portion 23! (see also Fig. 11) of the lever I31 to restrain said lever against clockwise move ment under influence of the levers I35 and I2? (Figs. 4 and 5) upontheir movement to release the carriage for tabulating movement. This retains the escapement control bar Hi l in its downward position, whereupon said bar, by means of the slot therein, in cooperation with the stud 35, likewise retains the tabulating stop bar |2;3 in its downward position. This holds the bars i 23 and i2 3 out of the path of the stop lug I22 on the control blocks l2! so as not to interfere I ith t u i amo e n of thgtra elinssab 15 riage through intervening columnar positions. When the traveling carriage 82 arrives at a predetermined columnar position after having skipped the intervening columns, mechanism controlled thereby and fully disclosed in the Christian Patent No. 2,082,098 rocks the latch 280 (Fig. 4) out of engagement with the bent-over portion 28I of the lever I31 to release said lever and the bars I23 and I24 to the action of the spring I41 (Figs. 4 and 5), which immediately moves said bars upwardly into the path of the lug I22 on the control block I2I corresponding to the predetermined columnar position. Thereafter the tabulating mechanism functions in a normal manner as explained earlier. When the bar I23 (Figs. 4, 5, and 6) is held in its downward position, as explained above, the slot in its lower end provides sufficient clearance for the stud I25, 0 as not to interfere with the usual and. necessary movement counter-clockwise and clockwise, re spectively, of the levers I38 and I21. Clockwise movement of the lever 521 depresses the bar I39 to disengage the escapement retaining pawl 91, in the manner explained earlier herein, to free the traveling carriage 82 for tabulating movement.

Balance and sub-balance keys The balance totalizer is selected and conditioned for balance or total operations by means of a Balance key I80 (Figs. 9, 10, and 12), and said totalizer is selected and conditioned for subbalance or sub-total operations by means of a Sub-Balance key IBI, the upper ends of the stems of said keys being undercut to engage corresponding slot in a key plate I82 secured to the left frame 38, and the lower ends of the stems of said keys being similarly undercut to engage corresponding notches in a horizontal portion of an angle bar I83, also secured to the left frame 30. Each of the keys I80 and I8I has a compressible spring I84 coiled around its reduced lower end. These springs are tensioned to urge said keys up wardly to undepressed positions, as shown here, which positions are determined by shoulders formed on the stems of said key by their undercut upper portions, in cooperation with the lower surface of the plate I82.

The Balance key i80 is a so-called motorized key, in that its depression initiates machine operations, the same as depression of any one of the release or starting bars 33, 34, or 35 (Fig. 1), as explained earlier herein. In sub-balance operations, it is necessary to depress both the Sub- .Balance key I8I and the Balance key I80, and this is effected by a finger I85 (Fig. 9), secured to the stem of the Sub-Balance key I8I, in cooperation with the underlying stud I86 secured in the stem of the key I80, through the medium of which depression of the Sub-Balance key I BI also simultaneously depresses the Balance key I80, to properly initiate a sub-balance operation in the balance totalizer.

The Balance key I80 (Figs. 9 and 12) has a notch I81 engageable by a bent-over ear I88 on a trip lever I89 free on a stud I90 secured in the left frame 30. A spring I9I urges the lever I89 clockwise to normally maintain the ear I88 in yielding contact with the forward end of a nonrepeat pawl I92 free on a stud I93 in the frame 38. A spring I94 urges the pawl J92 clockwise to normally retain the forward end of said pawl in the path of the ear I88 on the lever I89. The pawl I92 has a notch I95 engaged by a bent-over ear I96 on a pawl-operating arm I91 pivoted on a stud I98 in a bracket I99 secured to the Balance 16 key I80. A spring 200 (Fig. 12), tensioned between the arm I 91 and the bracket I99, urges said arm clockwise to normally maintain the ear I96 in engagement wtih the notch I95, as shown here.

Depression of the Balance key I (Figs. 9 and 12) causes the ear I96 to engage the downward wall of the notch I and rock the pawl I92 counter-clockwise, against the action of the spring I94, to move the upper end of said pawl beneath and out of the path of the ear I88 on the lever I89 to free said lever to the action of the spring 19!. Downward movement of the Balance key I80 likewise moves the notch I81 therein opposite the ear I88; consequently the spring I9I immediately rocks the lever I89 clockwise to engage said ear with said notch I81. Upon clockwise movement of the trip lever I89, the ear I88 engages the forward surface of the arm I91 and rocks said arm counter-clockwise, against the action of the spring 200, to move the ear I96 thereon out of engagement with the notch I95 and into a clearance recess formed in said pawl I92. Clockwise movement of the trip lever I89 causes a stud 20I, in a downward extension thereof, to engage an arm 202 secured on the left-hand end of a trip shaft 203, journaled in the main frames 29 and 30, and rock said arm and said shaft counter-clockwise as viewed in Fig. 12 and clockwise a viewed in Fig. 1. Clockwise movement of the shaft 203 and an arm 204 secured on its right-hand-end (Fig, 1) causes said arm, which is bifurcated at its upper end to embrace a stud 205 in a downward extension of the lever 48, to rock said lever counterclockwise against the action of the spring 49 to initiate machine operation in the manner explained near the beginning of this specification.

The pawl I92 (Fig. 12) and the arm I91 form a non-repeat device which permits the shaft 203 to be restored to untripped position at the end of machine operation in case the Balance key I80 is inadvertently retained depressed.

When clockwise tripping movement of the trip lever I89 (Fig. 12) rocks the arm I91 counterclockwise to disengage the ear I96 from the notch I95, as explained above, the spring I94 returns the pawl I92 clockwise until the upper edge of said pawl contacts the bottom surface of the ear I88. Therefore, the pawl I92 is free to move upwardly or clockwise under influence of the spring I94 into the path of the ear I88 when the lever I89 is restored counter-clockwise, as will now be explained.

Near the end of machine operation, the lever 48 (Fig. 1) is restored clockwise, in the manner explained previously, and, through the stud 205, restores the arm 204 and the shaft 203 counterclockwise as shown in Fig. 1 and clockwise as shown in Fig. 12, which movement of said shaft, through the arm 202 and the stud 20I, restores the trip lever I89 counter-clockwise, against the action of the spring I9I, to disengage the ear I88 from the notch I81 in the Balance key I80, to free said key for restoration upwardly by the spring I84 (Fig. 9). Inasmuch as the ear I96 (Fig. 12) of the arm I91 has previously been disengaged from the notch I95 in the pawl I92, said paw1 is free to move clockwise under influence of the spring I94, into the path of the ear I88, to obstruct releasing movement clockwise of said trip lever I89 in case the Balance key I80 is inadvertently or otherwise retained depressed at the end of machine operation. Thus it is clear that the above-described mechanism 17 prevents repeat operations of the machine when the Balance key I80 is retained depressed at the end of machine operation, either alone or in conjunction with the Sub-Balance key I8I, through the finger I85 and the stud I80.

Restoring upward movement of the Balance key I80 by its spring I84 (Figs. 9 and 12) carries the arm I91 upwardly in unison therewith, and, when the ear I96 on said arm moves into register with the notch I85, the spring 200 rocks said arm I91 clockwise to engage said ear with said notch, as shown in Fig. 12, in preparation for a succeeding balance or sub-balance operation.

Mechanism controlled by the Balance key I80 (Fig. 12) is provided for obstructing releasing movement of the shaft 203 when said Balance key is partially depressed, said mechanism operating alternatively to obstruct depression of said Balance key I80 upon releasing counter-clockwise movement of the shaft 203.

The stem of the Balance key I80 (Fig. 12) has secured therein a stud 201, which cooperates with the upper edge of an arm 208 free on a stud 209 in the left frame 30, said arm 208 being urged clockwise by a spring 2"! into yielding engagement with said stud 201. The arm 208 has a bent-over portion 2| I, which cooperates with the forward end of a finger 2I2 on an arm 2I3 secured on the release shaft 203.

When the Balance key I80 is in its upward position-that is, not depressed, as shown in Fig. 12 -releasing counter-clockwise movement of the shaft 203 and the arm 2I3 causes the finger M2 to pass beneath the bent-over portion 2 of the arm 208, to obstruct counter-clockwise movement (Fig. 12) of said arm. This, through the stud 201, locks the Balance key I80 in its upward position against depression and, through the stud I88 and the finger I85 (Fig. 9), likewise locks the Sub-Balance key I8I in its upward or und'epressed position. When either the Balance key I80 or the Sub-Balance key I8I is partially depressed, downward movement of said Balance key I80, through the stud 201, rocks the arm 208 slightly counter-clockwise to move the rearward edge of the bent-over portion 2'II into the path of the finger 2 [2 to obstruct releasing movement counter-clockwise, as viewed in Fig. 12, and releasing movement clockwise, as viewed in Fig. 1, of the release shaft 203, to prevent operation of the machine when either of said Balance or Sub- Balance keys is partially depressed. Full depression of either the Balance key I80 or the Sub- Balance key I8I, through the stud 201, rocks the arm 208 counter-clockwise sufficiently against the action of the spring 2I0 to move the bentover portion 2II beneath the finger 2I2, so as not to interfere with releasing counter-clockwise movement of the shaft 203 (Fig. 12) which movement causes said finger 2 I 2 to pass over the bentover portion 2II to secure said arm 208 in its counter-clockwise position during operation of the machine.

Automatic balance and sub-balance mechanism The present machine is provided with mechanism for depressing the Balance key I80 (Fig. 9) to initiate an automatic balance operation, and for depressing both the Balance key I80 and the Sub-Balance key I8I to initiate an automatic sub-balance operation. The above automatic balance and sub-balance mechanism is rendered efiective by the traveling carriage tabulating mechanism, shown in Fig. 4 and explained earlier herein, and is actuated by the traveling carriage upon 18 1 its arrival in predetermined columnar positions, or, to state it another way, the automatic balance and sub-balance mechanism functions only when the carriage is moved in a tabulating direction to predetermined columnar positions.

Directing attention to Figs. 3 and 4, adjustably mounted in predetermined columnar positions on the bar I20 are a sub-balance control block 2 and a balance control block 2I5, having pivotally mounted thereon, respectively, a sub-balance control tappet 2 I 0 and a balance control tappet 2I1, both of which cooperate with a horizontal extension 2I8 (see also Fig. '7) of an arm 2I8 free on a screw stud 220 threaded in the tabulating frame I25, said arm 2I9 having in its right-hand. end a, slot, concentric with the stud 220, which engages a guide stud 22I in the frame I25.

When the traveling carriage 82 is moving in a tabulating direction-that is, toward the right, as viewed in Fig. i -the control tappets H6 and 241 are firm and in this case engage the extension 2! and depress the arm 248 to actuate the automatic sub-balance and balance mechanisms, as will be explained presently. When the traveling carriage is moving in a return direction, or toward the left, as viewed in Fig. 4, the control tappets M5 and 2I1 are flexible and in this case bypass the extension 2I8 of the arm 2I8 without depressing said arm. Therefore, said tappets 2E8 and 2I'I are effective only when the traveling carriage 82 is moving in a tabulating direction.

Cooperating with the arm 2I9 (Figs. 4 and 7) is a companion arm 222 also pivotally supported by the stud 220 and having in its right-hand end a guide slot which engages the guide stud 22I exactly the same as the arm 2|9. Pivotally connected to a right-hand extension of the arm 222 (Figs. 4 and 7) is a switch operating bar 223 supported for vertical sliding movement in a slot formed in the left frame 30, the lower end of said bar 228 having secured thereto a switch operating block 224 made of suitable insulating material. The extreme lower ends of the bar 220 and the block 224 extend through a suitable opening in the base plate SI, and said block normally rests on an upper spring blade 225, which, together with a central spring blade 220, forms a balance switch for energizing a solenoid which depresses the Balance key, as will be explained presently. Likewise the central blade 226, together with a lower spring blade 221, forms a control switch for energizing a solenoid which depresses the Sub-Balance key, as will also be explained presently. ihe left-hand ends of the blades 225, 226, and 221 are secured in fixed relationship to each other by insulating blocks 220 in turn secured to a solenoid support plate 230 secured to the bottom surface of the machine base 3I by a plurality of screws.

In Fig. 2 is illustrated a. wiring diagram for the switch mechanisms and the corresponding solenoids, from which it may be seen that the central switch blade 226 is connected by a lead wire 229 directly to a source of electrical energy or input source. The upper blade 225 is connected by a lead wire 230 to one terminal of a balance solenoid 23l, the other terminal of which is connected by a lead wire 206 to a manually operable switch 232, in turn connected by a lead wire'233 to the other side of the source of electrical energy or input. The lower blade 221 is connect-ed by a lead wire 234 to one terminal of a sub-balance solenoid 235, the other terminal of which is connected by a lead wire 236 to a manu- 19 ally operable switch 231 in turn connected by a lead Wire 240 to the switch 232.

It is obvious from observing the wiring diagram (Fig. 2) that the switch 231 is not effective unless the switch 232 is closed, and that said switch 232, when closed, renders the balance solenoid effective, and that the switch 231, when closed, renders the sub-balance solenoid 235 effective. Therefore, when the switch 232 alone is closed, the balance solenoid 23! only is effective, and when said switch 232 and the switch 231 are both closed, both the balance solenoid 23! and the sub-balance solenoid 235 are eifective.

By referring to Fig. 2, it will be seen that a system of condensers is connected between the upper and lower switch blades 225 and 221 and the central switch blade 226, to improve the efliciency of the switch mechanism by preventing excessive sparking between the contact points thereof, thus eliminating the excessive radiation of undesirable interferences and noises.

' The balance and sub-balance solenoids 23! and 235 are secured to the bottom surface of the plate 233 (Fig. 9), and said solenoids and the switch mechanism 228 are enclosed by a suitable cover 239, secured to angular brackets 25! carried by said plate 238.

The balance solenoid 23! (Figs. 2, 9, and shiftably supports, in its hollow core, an armature 24'! connected by a closely coiled spring 242 to an arm 243, said spring, in this case, serving as a link. The arm 243 is secured on one end of a shaft 244 journaled in parallel side members 245 and 246 of a bracket 241 secured by screws 248 to the machine base 3|. Also secured on the shaft 244 is a crank 249 pivotally connected by a link250 to the Balance key I80. A stud 252 (Fig. 9) in the member 245 of the bracket 241, in cooperation with a slot in the arm 243, limits the rocking movement of said arm, the shaft 244, and the crank 249.

The sub-balance solenoid 235 shiftably supports in its hollow core an armature 253 connected by a closely coiled spring 254, similar to the spring 242, to a corresponding arm 255, said arm carrying a stud 256 journaled in a hub secured in the side member 246 of the bracket 241. The arm 255 is connected by a link 251 to the Sub-Balance key I8I. A stud 258 in the side member 246 of the bracket 241 cooperates with a slot in the arm 255 to limit its rocking movement.

The upward extension 2I8 of the arm 2| 3 (Figs. 4 and '7) is normally beneath or out of the path of the control tappets H6 and EH, except when the traveling carriage is moving in a tabulating direction. This is controlled by opposed camming surfaces formed in two similar slots 260 and 26! in the arms 2I9 and 222, respectively, in cooperation with a flattened stud 262, which extends through said slots and is secured in one end of a bar 263, the other end of which is pivoted on a stud 264 (Fig. 4) in an upward extension of a lever 265 free on a screw stud 266 threaded in the tabulating frame I25. A hook-shaped extension of the lever 265 has a slot which engages a stud 261 (Figs. 4 and 5) in the right-hand end .of the lever I21.

By referring to Figs. 4 and 5, it will be recalled that the traveling carriage 82 is released for tabulating movement by downward movement imparted to the operating arm I40, which movement rocks the lever I38 counter-clockwise and the lever I21 clockwise, as viewed here. Clockwise movement of the lever I21, through the stud 261, rocks the lever 265 counter-clockwise to shift the bar 263 and the stud 262 toward the left. The stud 262, coacting with the camming surfaces in the slots 260 and 26!, shifts the arms H9 and 222 in opposite directions to extend or l ngthen the operating connection between the tappets 2I6 and 2I1 and the switch mechanism formed by the extension 2I8 and the bar 223. This moves the extension 2I3 of the arm 2I9 upwardly into the path of the tappets 2I6 and 2I1, to effectuate the automatic balance and subbalance mechanism.

When the traveling carriage 82 (Figs. 3 and 4) nears the sub-balance columnar position, while movin in a tabulating direction or toward the right as viewed in Fig. 4, and just prior to the time that the stop lug I22 on the control block I2! for the sub-balance column strikes the stop bar I23, the sub-balance tappet 2I6 engages the extension 2I8 and depresses the arm 2I9, which, through the stud 262 (Figs. 4 and 7), in cooperation with the narrow portions of the slots 260 and 26!, simultaneously depresses the arm 222 to shift the bar 223 downwardly full distance. Full downward movement of the bar 223, through the block 224, engages the contact point of the blade 225 with the corresponding contact point on the upper surface of the central blade 226 and carries said central blade downwardly in unison therewith a sufficient distance to engage the contact point on the lower surface of said blade 226 with the corresponding contact point on the lower blade 221 (Figs. 2 and 4) to energize both the balance solenoid 23! and the sub-balance solenoid 235, Energizing of the solenoids 23! and 235 (Figs. 2 and 9) causes the corresponding armatures 24! and 253 to be displaced rearwardly or toward the left, as viewed here, which movement, through the corresponding springs 242 and 254 (Figs. 9 and 10), rocks the corresponding arms 243 and 255 clockwise. Clockwise movement of the arm 243, the shaft 244, and the crank 249, and such movement of the arm 255 (Fig. 9), through the corresponding links 250 and 251, simultaneously depress the Balance key I and the Sub- Balance key I8! to initiate an automatic subbalance operation.

At approximately the same time as the solenoids 23! and 235 function, the tappet I64 (Fig. 1) on the control block I2! for the sub-balance column engages the extension I65 to rock the lever I13 clockwise to free the lever 48 for counter-clockwise releasing movement under infiuence of the depressed Balance and Sub-Balance keys. Soon after the solenoids 23! and 235 have been energized and at approximately the same time as the latch lever I13 is moved to ineffective position, the stop lug I22 (Figs. 4 and 5) contacts the stop bar I23 to disengage the latch I43 from the square stud I42 to release the lever I21 to the action of the spring I33, which immediately restores said lever counter-clockwise in the manner explained earlier herein in connection with the traveling carriag mechanism, Restoring counter-clockwise movement of the lever I21, through the stud 261, rocks the lever 265 clockwise to shift the bar 263 and the stud 262 toward the right, as viewed in Fig. 4, to cause said stud 262 (Figs. 4 and 7) in cooperation with the'camming surfaces in the slots 260 and 26! in the arms 2I9 and 222, to lower the extension 2I8, out of the path of the tappets 2I6 and 2I1 to releasethe switch mechanism andthus render the automatic balance and sub-balanc mechanism ineffective. As the carriage settles in the 2t sub-balance columnar position, the lug-I22 en+ gages and releases the escapement control bar 24 (Figs. 4 and 11) to again render the esoapement mechanism effective to hold said carriage in said columnar position.

When the traveling carriage .is .moving inwa tabulating direction under influence of the typewriter escapement mechanism upon use of .the typewriter portion of the machine to type various data of a descriptive nature or otherwise upon the record material, it is evident that, even though the balance and sub-balance tappets2|1 and 2I6 pass over the extension 2I8, the autos matic balance and sub-balance mechanism will not be actuated, as the extension M8 is, in this case, retained out of the path of said tappets ZIB and 2H. Generally duringreturn movement of the traveling carriage toward the left, as viewed in Fig. 4, the extension 2I8 of the arm 2|9 is beneath the tappets 2E6 and 2|1. However, if for any reason said extension 2|8 is in its upward position in the path of said tappets, they will bypass said extension without imparting any depressing movement thereto, due to the flexible connection of said tappets to the corresponding control blocks2|4 and 2 5 (Fig, 4)

As a general rule, th balance column of the record material is the column next or adjacent to the sub-balance colunm of said record material, and, after the sub-balance has been automatically recorded in the sub-balance column, the traveling carriage is tabulated automatically from the sub-balance columnar position to the balance columnar position. Actuation of the tabulating mechanism causes the stud 262 (Figs. 4 and 7), in cooperation with the camming surfaces in'theslots 260 and 2G I, to move the extension 2|8 into the path of the balance tappet 2 I1 the same as'in sub-balance operations.

When the traveling carriage 82 nears the balance columnar position, and just prior to the time that the lug I22 on the corresponding control block |2| contacts the upper end of [the stop bar I23, the balance tappet 2|1, which, it will be recalled, is shorter than the sub-balance tappet 2|6, engages the extension 2|8 to depress said extension and the arm 2|9, which movement, through the narrow portions of the slots 260 and NI, in cooperation with the stud 262,'carrie s the arm 222 and the bar 223 downwardly in unison therewith. The tappet 2|1 (Figs. 4 and '1) moves the bar 223 downwardly a sufiicient distance to cause the block 224 to depressthe upper blade 225 just far enough to engage the contact thereon with the contact on the upper surface of the cen-v tral-blade 226, but not far enough to engage the contact on the lower surface of said central blade with the contact on the lower blade 221.

In this case, the closing of the contacts on the upper blade 225 and the central blade 226 through the circuit shown in Fig. 2, energizes the balance solenoid 23I, causing it to carry its armature 24I rearwardly. Rearward movement of the armature 24| (Figs. 9 and 10), through the corresponding spring 242, rocks the arm 243, the shaft 244, and the crank 249 clockwise, causing said crank 249, through the link 250, to depress the Balance key Hill toautomatically initiate a balance operation. Immediately after the balance solenoid 23! has functioned, the stop lug I22 (Fig. 4) on the balance control block |2| strikes the upper end of the stop bar I23, to restore the lcverI 21 (Fig; 5) counter-clockwiseto move the extension 2|8 of the arm 2 l9 out of the path :of the balance and sub-balance tappets 2| 1 22 and 2 |Z6,-in' exactly: the same manner as explained in :connection --with sub-balance operations;

A spring72BB::(Figs-. 9 and 1.0), tensioned be.- tween the armature 24| for the balance solenoid 23I and the side member 245 of the bracket 241, counterbalances the weight of said armature 24| to prevent excessive-frictional drag between said armature and the corresponding opening in the coreof said balance solenoid 23!, and said spring 2E8-likewise counteracts the downward pull of the spring 242' on said armature 24I. A spring 269-, tensioned between the side member 246 of the bracket 241 and the armature 253 for the sub-balahce solenoid 235, functions exactly like the spring 268 to-relieve said armature 253 from excessive frictional engagement with the opening therefor in the core of the sub-balance solenoid 235, and to counteract the downward pull of the spring 254'.

When an overdraft occurs in the balance totaliZer, the overallshaft 210' (Fig. 9) and a crank 21 I, secured lon said shaft, are rocked counter-clockwise. The crank 21I is connected by'a link 212110 a pitman 213, the rear end .of. which is supported by a slot therein in cooperae tion with'a stud 21:4 in the frame 30; The for-. ward end of the pitman213 is pivotally connected to the upper 'end of an toverdraft latch215 free on a stud zlt in the frame 38. Counter=clock wise movement of the-shaft 213 and the crank 211' shifts the link i212 and the pitman .213"rearwardl-y to rock the latch 215" also counter-clockwise. Counter-clockwise movement of the latch 215 (Fig. 9) engages a bent-over car 211 on its lower end with a locking notch'218 in the stem ofthe Balance key I] to lock said key against depres-' sion, either manually or by the balance solenoid 23|, when the balance totalizer is in anoven-i drawn condition.

Counter-clockwise movement of the overdraft shaft'21fl,'wh'en an overdraft occurs in the bale ance'totalizer, likewise-actuates mechanism which unlocks the Overdraft or Credit Balance key and the Sub-Overdraftor Sub-Credit Balance key so that either a sub-credit balance operation or'a creditzbalanoe operation'may be initiated to effect the recording of the true negative balance upon the record material supported by the platen 8|, as disclosed in the above-mentioned patent to Lehman, No. 2,243,806.

Control of machine releasing mechanism The present machine is provided with mechanism which functions when the Main starting bar 33 (Fig. l) is retained depressed at the end of machine operation, to cause the traveling car'- riageto be moved in a return direction to a pre-' determined columnar position. Likewise, the present machine is provided with mechanism which functions whenthe Skip Tabulatingbar 34 is retained depressed at the end of machine operation, to cause the traveling carriage 82 to be skip-tabulated to a predetermined columnar position.

In case either the Main starting bar 33 or the Skip Tabulating bar 34 is retained depressed at the end of machine operation, it is necessary to disconnect the lever 48- (Fig. 1) from said Main bar33, so that said lever, the arm 204, and the shaft 283 may be restored clockwise and counterclockwise, respectively, as viewed in Fig. 1, and so that said shaft 203 and the arm 2|3 may be restored clockwise, as viewed in Fig. 12. Restoration of the arm =2I3 moves the finger 2|2 thereon from':;beneath the bent-over portion2|| of the arm 208 to free the Balance key I80 for depression by the solenoid 23I (Fig. 9) in case the succeeding operation is an automatic sub-balance or balance operation.

It will be recalled that the release arm 88 (Fig. 1) is restored a slight distance beyond home position in a clockwise direction near the end of machine operation, and this movement, through a stud 283 carried by said arm 68, in cooperation with a rearward extension of a lever 284 free on the shaft 203, rocks said lever counter-clockwise. Counter-clockwise movement of the lever 284, through a notch in an upward extension thereof, in cooperation with a stud 282 in the latch 42, shifts said latch forwardly or toward the left, as viewed in Fig. 1, against the action of the spring 48, to disengage the hook-shaped upward extension 46 thereof from the stud 41 in the lever 48 to free said lever for return movement clockwise under influence of the spring 40, in case either the Main release bar 33 or the Skip Tabulating bar 34 is retained depressed at the end of machine operation. Clockwise restoring movement of the lever 48, through the stud 205 and the arm 204, restores the shaft 203 and the arm 2I3 counter-clockwise, as shown in Fig. l, and clockwise, as shown in Fig. 12, to move the finger 2I2 from beneath the bent-over portion 2II of the arm 208, to free the Balance key I80 for depression under the influence of the balance solenoid 23I (Figs. 2 and 9) in case the next operation is an automatic balance or sub-balance operation.

It is to be understood that it is the surplus or overthrow movement of the arm 68 in a restoring or clockwise direction which causes the stud 283, in cooperation with the lever 284, to move the latch 42 out of engagement with the stud 41, and that, as soon as said arm 68 is returned to untripped position, in which the shoulder 61 engages the stud 66, as shown in Fig. l, the stud 283 is withdrawn from the rearward extension of the lever 284 to permit the spring 49 to restore the 'latch 42 to efiective position, as shown here. The result of this is that, when pressure is released from the depressed bar 33 or 34, restoring upward movement of said bar, under influence of the springs 48 and 65, will cause the hook-shaped extension of said latch 42 to by-pass the stud 41, after which all parts assume the positions shown in Fig. l, in preparation for a subsequent machine operation.

By referring to Fig. 1, it will be recalled that, in case the Main release bar 33 is retained depressed (and naturally this applies to the Skip Tabulating bar 34 and the Vertical Feed bar 35, which also depress the Main release bar to initiate machine operation), the same overthrow movement of the arm 68 in a clockwise or restoring direction which disengages the latch 42, through the stud 58, disengages the bent-over portion 55 of the slide 56 from the fingers 53 and 54 and moves said bent-over portion into a clearance opening formed by said flanges. This disconnects the arm 51 from the arm SI and permits said arm 51 to be restored counterclockwise by the spring-actuated bell crank 63, independently of said arm to engage the stud 66, carried by said arm 51, with the shoulder 61 to retain the arm 68 and connected mechanism in home position and thus prevent a repeat releasing movement of said parts.

Ordinarily the tabulating arm I (Figs. 4 and 5) is actuated automatically near the end of machine operation to rock the levers I38 and 24 I2! counter-clockwise and clockwise, respectively, to release the traveling carriage 82 (Fig. 3) for tabulating movement after the printing mechanism has functioned. Prior to the automatic actuation of the tabulating arm I40, the latch 42 (Fig. 1) is disengaged, and the lever 48 and the shaft 203 are returned to normal positions, in the manner explained above, to insure that the finger 2I2 (Fig. 12) of the arm 213 is moved from beneath the bent-over portion 2 of the arm 2I3 before the sub-balance and balance tappets 2l6 and 2I1 (Fig. 4) have had a chance to contact the upward extension 2I8, so as not to interfere with the automatic depression of the Sub-Balance and Balance keys I8I and I80, in case the next operation is an automatic sub-balance operation or an automatic balance operation.

Summary of operation It is believed that a full understanding of the operation of the machine embodying the present invention will have been obtained by a careful perusal of the preceding specification. However, in summarizing briefly, it will be recalled that the control blocks 2M and 2I5 (Figs. 3 and 4), carrying the sub-balance and balance tappets 2 I6 and 2I'I, may be arranged or located upon the stop bar I28 in accordance with predetermined columnar positions of the record material supported by the platen roll 8|. When the traveling carriage 82, while moving in a tabulating direction, arrives at a position corresponding to the sub-balance column on the record material, the sub-balance tappet 2I6, in cooperation with the extension 2l6, depresses the bar 223 full distance downwardly to close the contacts between the blades 225, 226, and 221, to energize both the balance solenoid 23I and the sub-balance solenoid 235 to cause the Balance key I and the Sub- Balance key I8I to be depressed to automatically initiate a sub-balance operation.

Likewise it will be recalled that, when the balance tappet 2I'I (Fig. 4) engages the extension 2I8 while the traveling carriage is moving in a tabulating direction, the bar 223 will be depressed a partial distance to engage the contacts between the blade 225 and the blade 226 to energize the balance solenoid 23I to cause the Balance key I80 to be depressed to initiate an automatic balance operation.

It will also be remembered that the mechanism including the stud 261, the bar 263, and the stud 262 (Figs. 4 and 7) functions when the traveling carriage 82 is released for tabulating movement by the operating arm I40, causing said stud 262, in cooperation with the slots 260 and 26I in the arms 2I9 and 222, to move the extension upwardly from an ineffective position into the path of the tappets 2l6 and 2I'I. From this it is evident that the automatic balance and subbalance mechanism is eifective only upon release of the traveling carriage for tabul'ating movement by the accounting machine tabulating mechanism, and that said mechanism remains eifective only while said carriage is moving in a tabulating direction under the influence of said accounting machine tabulating mechanism. Therefore the automatic balance and sub-balance mechanism does not in any Way interfere with the use of the typewriter portion of the machine, as the letter-spacing movement of the traveling carriage (which is also in a tabulating direction) is not in any way influenced by or 251 dependent upon the accounting machine tabulating mechanism. j

While the 'form of mechanism shown and described herein is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the-invention to the one form or embodimentclisclosed herein, for itis susceptible of embodiment in various forms all coming within the scope of the claims which follow.

2. In a machine of the character described, having a balance totalizer capable of balance and/or sub-balance operations, and recording means positioned by the totalizer for recording balances and/or sub-balances, said machine also having a traveling carriage for supporting record material, said record material divided into various columns, including balance and sub-balance columns, said carriage movable to various columnew positions corresponding to the columnar divisions of the record material for presenting said columnar divisions to the recording means, the combination of members on the carriage corresponding to the various columnar positions thereof; means coacting with the members to locate the carriage in its various columnar positions, said means normally out of coa-cting relationship with said members; means to constantly urge the carriage in a tabulating direction; means nor-- mally effective to restrain the carriage against movement in a tabulating direction; means to release the restraining means and to simultaneously move the locating means into coacting relationship with the members to cause the carriage to tabulate to its various columnar positions; means to initiate a balance operation; means operable in conjunction with the balance initiating means to initiate a sub-balance operation; a separate solenoid for each initiating means; operating -'connections between each solenoid andits corresponding initiating means; a selectivelyoperable switch for connecting the solenoids to a source of electrical energy; a switch operating element located on the carriage in relation to the sub-balance column; a switch-operating element located on the traveling carriage in relation to the balance column; extendable means intermediate the elements and the switch to form an operating connection therebetween, said extendable means normally retracted so as to be ineffective; means operated by the releasingmeans upon its movement to release the restrain ing'means to extend the extendable means to form an operating connection between theele merits and the selectively operable switch, whereby movement of the carriage in a tabulating di-' rection to sub-balance columnar position will cause the sub-balance element to operate the switch in such a manner as to energize both the solenoids to initiate a sub-balance operation, in which the sub-balance is recorded in the sub-bal ance column of the record material, and whereby movement of the carriagein a tabulating direc-i tion to balance columnar position will cause the balance element to operate the switch in such a manner as to energize the balance solenoid to initiate a balance operation, in which the balance is recorded in the balance column of the record material.
